Explanation
of
the
columns
that
may
appear
on
this
page:
Lvl
A
few
code
lists
that
FHIR
defines
are
hierarchical
-
each
code
is
assigned
a
level.
For
value
sets,
levels
are
mostly
used
to
organize
codes
for
user
convenience,
but
may
follow
code
system
hierarchy
-
see
Code
System
for
further
information
Source
The
source
of
the
definition
of
the
code
(when
the
value
set
draws
in
codes
defined
elsewhere)
Code
The
code
(used
as
the
code
in
the
resource
instance).
If
the
code
is
in
italics,
this
indicates
that
the
code
is
not
selectable
('Abstract')
Display
The
display
(used
in
the
display
element
of
a
Coding
).
If
there
is
no
display,
implementers
should
not
simply
display
the
code,
but
map
the
concept
into
their
application
